Locking Down the Desktop: Disabling GNOME
Desktop Features
The GNOME desktop can be configured to restrict user access to a number of actions, such as print-
ing, access to the command line, and even the ability to log out of the system. The most restricted
configuration can be used to form the basis for a public terminal configuration or that of a kiosk-like
setup, in which the user can only perform simple functions like web browsing. This chapter provides
the essential information needed by administrators to perform the various tasks related to locking
down the desktop.
Most of the restricted access can be configured using GConf key/value pairs, hence these will be
discussed first.

To disable the ability to log out and to lock the screen, set the appropriate keys under
using the GConf editor.
